Hello,

Let's f(x)=n(x)/d(x)

Discontinuities are found as zeros of d(x)
Zeros are zeros of n(x)

Ralph likes 25 but not 24;400 but not 300;144 but not 145; does he like 10,50,124,200, or 1600

Likurg_2 [28]

25, 400 and 144 are all square numbers and 24, 300 and 145 are not.

Therefore, he must like 1600

Answer:

6.13

Step-by-step explanation:

Using Sine Law we know that

$\dfrac{a}{SinA}=\dfrac{b}{SinB}=\dfrac{c}{SinC}$

Using your figure let's assign sides and angles:

A=? B = 60° C = 70°

a = 5 b = ? c = x

If we put that into our formula:

$\dfrac{5}{Sin?}=\dfrac{?}{Sin60}=\dfrac{x}{Sin70}$

Notice that we have too many unknowns. We need to complete at least one ratio to do this, so how do we do this?

Notice we have 2 angles given, so we solve for the third angle. The sum of all angles in any triangle is always 180°

∠A + ∠B + ∠C= 180°

∠A + 60° + 70° = 180°

∠A + 130° = 180°

∠A = 180° - 130°

∠A = 50°

Now we can use this to solve for x.

$\dfrac{5}{Sin50}=\dfrac{x}{Sin70}\\\\\dfrac{(5)(Sin70)}{Sin50} = x\\\\\dfrac{4.6985}{0.7660}=x\\\\6.1338 =x$

So the closest answer would be 6.13

Which of the following must be true?

Ilya [14]

The answer is C, when numbers or variables are between "|" (also called bars) it means to remove any negative symbols and think of it as a positive number. If the number is already positive you keep it a positive number.
